I am upgrading my figure 8 puffer from a 10 gallon to a 20 gallon tank. In his 10 gallon with regular factory light/hood, there is a terrible brown algae problem. It can easily be wiped off the glass and rocks during weekly water changes, but it's pretty unsightly by the time that comes around. Since I'm starting from near scratch on this new tank, what sort of lighting should I get to combat this problem from the start?
